![]() Pneumatic retinopexy, scleral buckling, and vitrectomy are established modalities of treatment for retinal detachments. Examples include inflammation, vascular injury, and choroidal tumors. Any disease of the retinal pigment epithelium and the choroid can damage the blood retinal barrier and overwhelm the retinal pigment epithelium pump, resulting in fluid accumulating under the retina. The retinal pigment epithelium is responsible for pumping fluid out of the retina so that the retina and retinal pigment epithelium remain attached. These detachments result from diseases of the retinal pigment epithelium and the choroids. These detachments occur when scar tissue contracts and induces mechanical traction on the neurosensory retina, thus pulling the retina from the retinal pigment epithelium.Īn exudative retinal detachment occurs in the absence of either retinal breaks or vitreoretinal traction. Studies have reported that approximately 6% of all eyes have a retinal break, but only 1 person in 10,000-15,000 a year eventually requires retinal detachment repair.Ī tractional retinal detachment is caused by direct mechanical traction. Any retinal break or tear can cause a retinal detachment. They occur with an incidence of 5-10 per 100,000 population/year. ![]() Most detachments generally are of the rhegmatogenous type. The accumulation of fluid in the subretinal space results in the separation of the retina from the retinal pigment epithelium. There are 3 kinds of retinal detachments: (1) Rhegmatogenous, (2) Tractional, and (3) Exudative.Ī rhegmatogenous retinal detachment results when a tear or break in the retina occurs, resulting in vitreous fluid gaining access to the subretinal space.
